Equinox and Solstice
What is an equinox?
An equinox is a time of year when day and night are approximately equal in length, occurring twice a year.
What is a natural hazard?
What is a natural hazard?
What are the main layers of the Earth?
The main layers of the Earth are the crust, mantle, outer core, and inner core.
How does weathering impact soil formation?
Weathering breaks down rocks into smaller particles that contribute to soil formation.
What is a landform?
A landform is a natural feature of the Earth's surface, such as mountains, hills, valleys, and plains.
What is a solstice?
A solstice is a point in the year when the sun is at its highest or lowest point in the sky at noon, resulting in the longest and shortest days.
How can communities prepare for natural hazards?
Communities can prepare by creating emergency plans, building safe structures, and educating the public.
Which layer of the Earth is solid and made of rock?
The crust
Explain how erosion can shape landforms.
Erosion can shape landforms by carving out valleys, canyons, and creating hills or cliffs as soil and rock are removed.
What causes faults to form?
Faults form due to stress and pressure on the Earth's crust from tectonic forces.
Which two months do equinoxes typically occur?
Equinoxes typically occur in March and September.
Name one example of a natural hazard.
An example of a natural hazard is a hurricane.
What is the main component of the Earth's outer core?
The outer core is primarily made of liquid iron and nickel.
Name a landform created by deposition.
A delta is a landform created by deposition at the mouth of a river.
How can faults lead to earthquakes?
When stress builds up along a fault and is released, it causes an earthquake.
How do solstices influence climate?
Solstices influence climate by marking the change of seasons and affecting temperature and daylight.
What role does technology play in predicting natural hazards?
Technology helps predict natural hazards through monitoring systems, satellite imagery, and computer models.
What is the temperature like in the Earth's inner core?
The inner core is extremely hot, with temperatures reaching up to 5,700 degrees Celsius
What is erosion?
Erosion is the process of moving soil and rock from one location to another, often by wind, water, or ice.
What is a volcano?
A volcano is an opening in the Earth's crust through which molten rock, gases, and ash can escape.
When does the summer solstice occur in the Northern Hemisphere?
The summer solstice occurs around June 21.
Why is it important to study natural hazards?
Studying natural hazards helps us understand them better, which can lead to improved safety measures and disaster response.
How does the movement of the Earth's mantle affect the surface?
The movement of the mantle causes tectonic plates to shift, leading to earthquakes and volcanic activity.
What are the two main types of weathering?
The two main types of weathering are mechanical weathering and chemical weathering.
What are tectonic plates?
Tectonic plates are large sections of the Earth's crust that move and interact with each other.
